An IfcCostItem can be used to represent the cost of goods and services, the execution of works by a process, lifecycle cost and more. Each instance of IfcCostItem can have a name and a description. Depending on the use for which the cost is intended, these values should be asserted on the basis of agreement. For instance, the Name attribute could be used to provide a common value that enables distinct instances to be brought together in a nesting arrangement while the Description attribute can be used to provide text used for item description in a costing schedule. - Classification - The Classification Association concept applies to this entity. Instances of IfcCostItem are used for cost estimates, budgets, and other forms, where a variety of identification codes are used extensively to identify the meaning of the cost. Examples include project phase codes, CSI codes, takeoff sequence numbers, and cost accounts. The model allows for all classes that are ultimately subtypes of IfcObject to inherit the ability to have one or more instances of IfcClassificationReference to be assigned. Where identification codes are required, the generic IfcRelAssociatesClassification facility should be used. - Control Assignment - The Control Assignment concept template applies to this entity as shown in the table below TypeDescription IfcProduct For quantity-based costs based on product occurrences, spatial structures, or other physical artifacts IfcProcess For quantity-based costs based on tasks, procedures, or events IfcResource For quantity-based costs based on resource allocations IfcTypeProduct For cost rates based on product models IfcTypeProcess For cost rates based on process models of historical or projected duration IfcTypeResource For cost rates based on resource models of historical or projected productivity
The figure below illustrates cost item assignment derived from building elements. The IfcRelAssignsToControl relationship indicates building elements for which quantities are derived. Costs can also be derived from building elements by traversing assignment relationships from the assigned IfcProduct to IfcProcess to IfcResource, where all costs ultimately originate at resources. It is also possible for cost items to have assignments from processes or resources directly. */ class IFC2X3_EXPORT IfcCostItem : public IfcControl { //DOM-IGNORE-BEGIN OD_EXP_DECLARE_MEMBERS(OdIfc2x3::IfcCostItem); //DOM-IGNORE-END public: /** \details Returns a type of a class instance. \returns Pointer to the OdDAI::Entity type that determines an entity definition within a schema. */ virtual OdDAI::Entity* getInstanceType() const override; /** \details Early-bound version of instances comparison. \param pOther [in] Other application instance. \param ordering [out] Receives the ordering (comparison) status. \returns true if comparison was performed, false if method has no implementation, so late-bound version could be applied. \remarks If the method returns true, the ordering parameter can receive one of the following statuses: Name Value Description _kLessThan_ -1 This object < Other Object. _kEqual_ 0 This object = Other Object. _kGreaterThan_ 1 This object > Other Object. _kNotOrderable_ 2 This class is not orderable.
